riscv: Fix arch_fixup_fdt always failing without /chosen

Browse Source 
If /chosen was missing, chosen_offset would never get updated with the new
/chosen node. This would cause fdt_setprop_u32 to fail. This patch fixes
this by setting chosen_offset. In addition, log any errors from setting
boot-hartid as well.
